    Sammanfattning : Pressing demands on electrical energy storage require high power and high energy density rechargeable batteries with improved safety, reliable performance and low cost. This has led to reconsiderations in the choice of battery chemistry and battery design. LÄS MER

  4. 3. Atom transfer radical polymerization from multifunctional substrates

    Författare :Anna Carlmark; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Polymer chemistry; Polymerkemi;

    Sammanfattning : Atom transfer radical polymerization (ATRP) has proven to be a powerful technique to obtain polymers with narrow polydispersities and controlled molecular weight. It also offers control over chain-ends. LÄS MER

  5. 4. Photocuring of multifunctional monomers initiated by camphorquinone / amine systems for application in dental restorative resins

    Författare :Nie Jun; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Photocuring; Dental restorative resins; Photoinitiator system: Cainphorquinone amines; Monomers: Meth acrylates; Photoinitiated polymerization kinetics;

    Sammanfattning : This thesis deals with the photopolymerization of mono-, di- and trifunctional monomers initiated by carnphorquinone (CQ) alone and/or with different amines (AMH) as coinitiators in air as well in nitrogen. The kinetics of photopolymerization was measured by photoisothermal calorimetry (photo-DSC), which allowed the measurement of the rate of polymerization (Rp), maximum rate of polymerization (Rpmax), time of inhibition (tinh), time at which Rpmax was obtained (tmax), double bond conversion (p) and maximum double bond conversion (pmax).
